This invention relates more particularly to the equipment'of adding andlisting machines and'the like l'for'handling various work sheets suchfor example, as ledger *sheets, bills,-;record or proof sheets and thelike.

It has been customaryheretofore to. as-

251 1 The rinci a'l ob'ect of'mv'invention is feeding means.

to provide equipment whereby the work sheets \Inay becollate'd in awork-sheet holder while. out-iofpthe machine,;-the holder being" readilytransferred from a collating =table.to"the 'niachineland adapted to hold.sembled relation in the work-sheet holder.

The latteris provided with retaining devices for holding the work sheetsin their adjusted positions relative to each other. The holder istransferredto the machine and is so supported thereon that the worksheets are located between .the platen and cooperating feed rolls, theplaten being then in its rearposition to permit ready insertion of theholder and sheets. hen the platen'cr adle is rocked forward to bring theplaten into print-in position and into cooperative relation with thefeeding rolls tae retaining device on the holder are automaticallydisabled by an arm on the platen cradle so that the collated sheetsnutty be while another holder as on the line 'oonm'rmeimnrrmsnr roaADDING MACHINES AND THE LIKE.

One ofthe sheets, forexamplefthefi ASSIGNOR TO BURROUGHS ADDI NG MA tally or proof sheet,-maybe curled around i and fed by 1 the platen in the usual way.'.Another object of the invention is to-pro 0o vide an improved work-sheetholder adapt-* ed to retain the work sheets collated con 1 dition. i

Still anotherobject ofmy invention-is to provldean improved collatingtable upon which the work-sheet holdermay be supported iii-properposition and which is provided with means facilitating the positioningof the sheets with Othelt;

With the above and incidental objects in view, the invention consists incertain novel features of construction and combirespect to each" nation-0f parts, the essential elements= whereof are recited in the appendedclaims and a preferred form of embodiment of illustrated-in full in theaccompanying drawings which form part of thisspecification.

The invention is shown herein- 2.5 applied. to the well-known ,Burroughsadding and listing machine, but,it' is understood that it is not limitedinits gapplica-tion thereto as'it is adapted foruse on other typesof.-adding 1 and listing machines as well as on typewriters and thelike.My invention is also adapted for use inhandling ,various bookkeepingsystems, but, for convenience, I will describe its usein connection withhandling the boolrkeeping work 'ofcustomers accounts, in which casethree sheets (the cus tomers bill-101' statement, the customersledgersheet and the proof or tally sheet) are printed upon, thestatementand ledger sheet being collated on the collating table, whilethe proof sheet is curled about'and-fed by the platen in the usualmanner.

In view of the fact that the Burroughs machine is in extensivecommercial use and is well known, it will be wholly unnecessary todescribe the machine properpr to describe the carriage equipmentin anydetail. Referring to Fig. 1, the adding machine, designatcd generally bythe reference numeral 20, is supported on the usual stand or rack 21.The usual numeral keys 22 are employed for setting up the various itemsand controlling the extent of movement of the customary actuating leverswhich carry type plates 23 (Fig. 8) for presenting items and totals tothe printing line. A back panel 24 (Figs. 8, J and 10) of the supportingframe work of the machine has secured to it.

the usual track 25 upon which the laterally siiiftable paper carriage 26runs, the track and carriage having the usual raceways in which rollerbearings are mounted. A rotating platen 27 is supported in the rockframe or. cradle 28, which comprises end plates 29 journaled on across-shaft 30 carried by the end plates of the carriage 2G. The cradle28 carries a paper support or back 32 upon which are mounted laterallyadjustable guides as shown or described more fully in my Patent No.1,208,375,

11, the sheets being shown clamped,

.platen with the usual pressure rolls 35. The forwardiends of the proofsheet and carbon.

are guided by a floating pan 36 carried by the platen cradle, and arealso guided by wellknown guide fingers 37, supported at .their rearupper ends on a cross-rod 38 and having their forward lower edges offsetto slightly overlap the upper forward edgeof thefioating pan 36. -T herod 38 is supported in extensions of the side plates 29 of the platencradle. Upon each operation of the machine, the platen 27 is rotated tolinespace the proof sheet, and also thestatement and-ledger sheet, aswill be described later,-

the platen being rotated by the usual linespacing mechanism which isonly shown generally in Fig. 1 and which is designated by the referencenumeral 39. The pressure or feed rolls are supported by levers 10 andare pressed against the carbon and: proof sheet by the usual springs 41,(Fig. 9).as is customary in'rthis type of Burroughs machine.

The platen cradle 28 may berocked so that it is either in its forwardprinting position, shown in Fig. 10, or in its rearward positionillustrated in Figs. 8 and 9. In order to hold the platen firmly in itsprinting position, a' roller 42 (Fig. 8) is firmly held against the camedge 43 of the left hand ,plate 29 by a spring 44 connected to the arm45 carrying tne roller, this construction being also common to this typeof Burroughs machine.

In order to latch the platen cradle in its rearward position I employthe latching mechanism illustrated in Fig. 8, the platen being thereshown latched in its rcarwardly tilted position by a latch 46, pivotedat 17 to the right-hand vertically extending side plate or arm 48, thearms 48 being secured to the side. plates of the paper carriage. Thevertical arm of the latch carries an operating finger piece 49 and isprovided with a slot. 50 through which the shouldered stud 51 projects,the stud serving as a stop for limiting the forward or releasingmovemcnt of the latch. The rear end of the horizontal arm of the latchhas a shoulder 52 which, when the platen cradle is tilted back, engagesa headed stud 53 on the right side plate 29 of the platen cradle, thelatch being moved to such latching position by a spring 54.

In addition to the paper table 32, the paper carriage is provided with;another paper guide or plate 57 which extends above the platen and hasits upperend rolled about a cross-rod '58, carried by the side arms 48,wliilethe lower edge is curved'forwardly to;avoidr-inter-ference withthe-platen when the, platen is; in its printing position. A cross-rod 59is supported at its ends in rearweirdly extending arms; 60 integral withthe 59 projects through rcarwardly extending'ears- 51 0f two paper:

guides 62, best shown in Fig; 2.

together: with an interposed carbon C held in position thereon, and theplaten cradle in its .rearwardly tilted position, the lower portions ofthe bill and ledger-sheet are guided by a table GT, which is niounted onthe and screws '70. The table comprises acurved plate? 1' and twoparallel plates 72, which are supgiortedon and over the edgeportions ofthe lower plate 71 through spacing collars 73 located along the edges ofthe plates.

Equaliy spaced along the upper edge of theplate 71 are fourspring-pressed feeding i'olis 7 1, the rolls being mounted on arms 75whi h are engaged by leaf springs 'l'fiunorinaliy tending to press therolls towards the platen.

I I; f

ls hile theledger sheet and statement are being positioned and collatedin the holder,

the pins 85 andpads 86 are in the elevated lmliltloli illustratedin Fig.4 and are retained in such position by en agement of the shinilde'r 9:5with the underside of the rightlmnd arm 84-. A projecting nose 93 thenx-ngages the side edge of this arm to limit 115 the increment of thelatch'9l in one direction while a pin 92' liinitsmiovemcnt oftlic latchin the other direction After the ledger sheet and the statement havebeen ,propei'iy positioned. the latch 91 by he finger-piece 92 to carrythe shoulder 9-; from under the arm 84, whereupon a spring 95,compressed between the plate 78 and the upper arm of the lever 88, rocksthe arms Stand shaft 83 to-niove the pads 86 into tirni engagement withthe work sheets to press them against the plate79, as shown in Fig. 5.The pointed ends of the pins 8;; pierce the work sheets and thus the 1.:is moved pads and pins hold the work sheets in then-U holder and theledger sheet and statement in the positions illustrated in Fig. 9. Whenthe platen is moved from its-rear position, shown in Figs. Sand 9, toits tron, shownin :Fig. 10, adog or arm 97, se-

cured to the :shaft 38, is moved through the slots 89 and intoengagement with the rear side of the longer'arm of the lever 88, thusrocking the lever shait 83 -and.arms 84 in opposition to the spring 95'and thereby raising the pads 86 and the pins-85 from contact with thestatement; In'this'way the ledger sheet and the statement are releasedfrom the work-sheet holder and they may then be fed by rotation of theplaten, the roll 74 then being in contact with the statement. Thus theledger sheet and statementsheet, as well as the proof or record sheet,are fed in unison by rotation of the platen and the collated conditionof the ledger sheet and statement is maintained.

When the platen is moved to printing position, the armor dog 97 rocksthe arms 8-1 to move the pads 86 and pins 85 out of engagement with thework sheets but not sufficiently to permit the shoulder 93 of the latch91 to snap under the righthand arm 84 so that when the work sheets areto be removed from the machine the platen cradle is rocked rearwardlycarrying'the dog 97 out of engagement with the lever the spring torockthe arms 84 and move the pads 86 and pins 85 into engagement with thework sheets in the work-sheet hold er. Thus. when the platen is movedaway from the feed rolls 7 1, the ledger sheet and bill are againclamped in the work-sheet holder before they are released from theplaten and feed rolls 74 and may be removed from the machine with theholder. Then to release the work sheets from the holder the arms 84 maybe rocked manually through the lever 88.

('ollvuing table.

Mounted on one of the side bars of the stand 21 is a bracket. 98 1)which is firmly secured in position on the bar by any suitable means..The bracket 98 carries a vertical pin 100 to which a split collar 101is secured. The collar carrie a laterally extending rod 102 on which issecured a yoke 103 (Fig. 12), the yoke being secured in adjustedposition on the rod 102 by means of set screws 108 carried by thecollars on the arms of the yoke. Secured to the yoke printing posi- 88to permit which three bolts 108 project. A triangular- 1 and 12) throughshaped finder plate 109 is supported along its left-hand edge on bolts108 project through transverse slots 110'in the finder plate 109'topermit lateral adjustment of this: plate.'--'Mountedon the left-hand endof the finder plate is a strip 111 which supports a second finder plate112. Two elongated slots 113, extending tit-right angles to the slots110, are formed in the plate 112 and permit adjustment of the plate.:The finder plate 109 has an' opening 114 and thefinder plate 112 has afinder houlder 115.

In order to collate the-ledger sheet and he statement, the ledger sheetL is first the bar 107 and the placed on the collating table and underthe piate 109, the rear portion of the ledger .-.heet being inserted inthe work-sheet holder.

The left-hand edge of the ledger sheet is with the right-hand broughtinto contact edge of the strip 107 and also with the rightband edge -'ofthe left-hand spacing strip 80 on the holder in order to align theledger sheet straight in the holder. Riveted or otherwise secured to thestrip 107 is a spring arm 10? (Figs. 1 and 7) carrying a pres sure pad108', the arm being pressed down by the finger of-the operator to forcethe ad against the ledger sheet and hold it while the statement andcarbon are being adjusted.

The shaft 83, mounted on the holder, is provided with an arm 116provided with a downwardly extending guide lug 117 which has its lowerend curved so that when the ledger sheet is inserted its rear endengages the curved edge of the guide and is defiected downwardly asindicated in Fig. 4. The last line printed on the ledger sheet isbrought into line with the straight edge 118 of the opening 114. Thestatement B with the carbon C is now inserted over the plate 109 andunder the finder plate 112 with their left-hand edges in engagement witha vertical flange 120 on the plate 109 and also in engagement with theside of the guide lug 117. The last line printed on is brought intoalignment with the shoulder 115. The plate 109 is adjustable laterally,due to the slots 110, and the arm 116 may be slid on the shaft 88 andsecured in adjusted position thereon by a set screw 116, in order toaccommodate statements of diflerent widths. \Yhen the latch 91 istripped and the arm 116 rocked to the position shown in Fig. 5

and when the shaft 83 and arm 116 are rocked by the dog-'97, uponmovement of the platen to printing position, lag 117 is not-movedsufficiently to engage These work sheets and hence-cannot interfere withthe feeding of the work sheets by the platen.

" Modified form, of z oi'lli-shecz fielder.

I-- have' 'illustrated a modified form of worksheet holder in Fig. 11and Figs. 13 to 16. The frame of this holder comprises parallel plates78 and 79 as in the preferred .form.-' In this modified form two stripsI25fof spring metal are riveted or otherwise'seeured to the plate 78 andtheir forward ends':are provided with inwardly ezitendingpoints 126 and126,"which are adapted to enga e and retain the work s'heetsi-incollate1 condition. Levers 127 and 127'are centrally pivoted on the plate 78and their'respective outer ends are adapted to engage with the lowerinclined or cam edgesfof downwardly extending flanges 129 formed-onrtherespective strips 125. The inner end of the lever 127 carries a pin 128projecting into a recess formed in the inner end ofthe other-lever 127.A spring 131, connected' 'at oneend to the lever 127, tends tohoid thelevers-in the positions shown in F 11 so-thattheir outer ends are out ofcontactwith the flanges 129, as indicated in Fig. 14. Theinner end ofthe lever 127 carries a downwardly projecting stud 132 in front of whichprojects one end of the lever 133 pivoted at 134 to the plate 78.

The right-hand end of the lever 133 is of irregular shape, beingprovided with a rearwardly extending portion having a verticallinger-piece 135 and with :1. forwardly extending portion provided witha slot 136 through which projects a stud 136 in order to assist inguiding the lever in its move nients. This forwardly extending portionis also provided with an ea 137 from which laterally projects a rollerstud 138 e. :tcnd ing over the slots 89 formed in the plates 78 and 79.Pivoted at 140 on the plate 78 is a latch 141, the rear end of whichprojects beyond the holder in order to permit manual operation of thelatch. A leaf spring 142 engages the latch and tends to rock it in aclockwise direction.

While the ledger sheet and statement are being adjusted on the collatingtable, the parts are in the condition illustrated in Fig. 15, the points126 and 126 then being elevated out of engagement with the work sheets.At this time the forward end of the latch 141 engages behind a shoulder145 on the lever 133, thus latching the levers 127 and 127 in suchcondition that their outer ends are under the forward ends of theflanges 129 to hold the forward ends of the spring arms 12:? in elevatedposition with their points 12-6 and 126 out of contact Willi the ledgersheet and statement.

Th:- latch 141 is now Ma -pod by the operator, whereupon the spring 131moves the parts to the positions shown in Figs. 11 and 14, in whichcondition of the parts the outer ends of the levers '127'and 127have-*been moved rcarwardiy out of engagement with the flanges 129, sothat the forward ends of the strips or arms 125 spring downwardand thucause their points 126 and 126 to'partially pierce the work sheets andinterposed carbon. The worlesheet holder, with the work sheets held inposition, is nowtransferred to the machine, and-when the platen is movedto printing position the dog-97 (Fig. 15)- which is similar to the dog"*97 shown in Figs. 8, 9 and 10, is projected through the slots 89 andengagesover'the roller stud 138, forcing it downwardly with the resultthat the lever 133' is rocked clockwiseto the position sh'own'in Figf16. It will be noted, by observingthis figure, that the lever 133 isnot rocked suflieiently by the dog 97 to permit the latch 141 to snapbehind the shoulder 145, sothat when the dog 97 is moved out ofengagement with the roller stud 138, the spring '131 rocks the levers127-.and 127' to raise-their outer ends whereupon the points l26 and126' again pierce the ledger sheet and statement which may then beremoved-from the machine with the work-sheet holder. The ledger sheetand statement may next be released from these retaining devices by man'-ually operatng the lever 133 which is then latched in releasingcondition by'the latch 141.

An arm 149 (Figs. 11, 14c and 15) corresponding to the arm 11(3 of thepreferred form, is loosely mounted on a pin 150 and is normally pressedagainst the plate 78 by a leaf spring 151. The guide lug 117 on the armdirects the rcar or top edge of the ledger sheet downwardly when (heledger sheet is inserted in the holder and the left-hand edge of thestatement engages the side of the lug to aid in aligning thestaten'icnt. The arm 1 19 is spring-pressed against the plate '78 sothat it may yield when the ledger sheet and statement are fed by thevplaten in case there is undue friction between the ledger sheet and theguide lug 117, and thus the arms 149 does not interfere with the feedingmovement of the work sheets.

It is to be understood that thecmbodiments of the invcntion hcreindescribed, are susceptible to various modifications without departurefrom the scope and spirit of the invention as defined in the appendedclaims.
